[PATCH] smb: client: fix sbflags initialization

[Arnd Bergmann <arnd@kernel.org>]

From: Arnd Bergmann <arnd@arndb.de>

The newly introduced variable is initialized in an #ifdef block
but used outside of it, leading to undefined behavior when
CONFIG_CIFS_ALLOW_INSECURE_LEGACY is disabled:

fs/smb/client/dir.c:417:9: error: variable 'sbflags' is uninitialized when used here [-Werror,-Wuninitialized]
  417 |                                 if (sbflags & CIFS_MOUNT_DYNPERM)
      |                                     ^~~~~~~

Move the initialization into the declaration, the same way as the
other similar function do it.

Fixes: 4fc3a433c139 ("smb: client: use atomic_t for mnt_cifs_flags")
